FREDERICK A! ADDING APPARATUQ.

SPECIFICATION forming part of Letters Patent No. 669,286, dated March 5, 1901.

Application filed September 29, 1399. Serial No. 732,127. (No model.)

To 60% whom; it may concern.-

Belt known that I, FREDERICK H. SAND- HERR, of St. Louis, in the State of Missouri,

have invented anew and useful Improvement in Adding Apparatus, of which the following is a specification.

My invention is an improvement in calculators, being in the nature of an improvement in adding-machines having recording orprint- IO ing devices arranged to cooperate with the printing devices of a type-writer anti including in the embodiment shown a total mech-- anism, so the machine may be employed for ordinary writing, for ordinary adding, for tabulating the figures of'addition and striking the total, or, in the making out of accounts and statements, for producing the text, the tabulated figures, and the totals as may be desired.

Theinvention consists in certain novel constructions and combination of parts, as will be hereinafter described, and pointed out'in the claims.

In the accompanying illustration l have F the spring-drum, as will he understood from represented myinvention as em bodied in connection with a type-Writing machine of the Remington form; but I purpose in the drawings to illustrate the invention as embodied in that class of type-Writing machines generally recognized as basket -machines, in which the type-bars range around or form a basket and'opcrate to the center of the same; but it should be understood that I 'do not wish to be limited in the broad features of my invention to the specific form of typewriting machine shown, as the adding and recording or printing mechanism can readily be adapted to other forms of type-writing machines without departing from the spirit of my invcnion.

By my improvement I seek to provide a simple construction by which to accurately add any sum within the range of the machine, strike and print the several factors. and the sum total, and to effect the printing in such relation to the printing devices of the typewritiug machine as to enable the coii'peration of the printing devices of the adding mechanism with those of the type-writing machine in stating accounts and other tabulated state ments where the figures and text are combined in forming the statement.

In the construction shown I employin conncction with the framing of the type-writing machine a framing composed of two side plates 11 and 1;, which may be cast integral with the framing 10 or be made separate and suitably secured in place. The main shaft 12) is journalcd in the side plates 11 and 12 and is given a tension in the direction indicated by the arrow it in Fig. '7. In connec- Tion with this main'shaft 13 I provide an escapemcni releasing mechanism (shown in Figs. 21, 22, and and hereinafterdescribed) which permits the shaft to turn with a stepbvstep motion in the direction indicated by The length of the steps or movement of the shaft at each operation may vary according to the kejv struck, the said shaft moving from one to nine times the unit distance, according to the figure it is desired to add. The shaft 13 is orivcn in the construction shown by a sprii'ig-drum 15, which has a shaft lo and a gear 17, meshing with a pinion 18 on the shaft 13. The drum may he wound by any suitable form of key Whenever necessary, a handle 19 being shown on the shaft ll; of the drum in the present instance; bill I find it desirableto furnish means for automatically winding the drum by the operation of the printing (.leviccs oi the adding mechanism. To this end I furnish a pulley 20, clutched on the shaft 16, operated in one direction by the spring 21 and in the other diwction by a chain connection 22,with a pulleysiwtion :23 in the shaft of the lever lor opera inc' the printing devices of the addin nnscnanism, so that each operation of the sa. printing devices will serve to wind Figs. 17 and 18 of the drawings.

The operating-wheel 2b is keyed on and slidable along the main shaft 13, as shown in dotted lines in Fig. 5, so it can be set into mesh with any of the carrying-disks 27. These disks 27, of which I have shown six, are alike and are designed to count from units at the left when viewed from the rear, as in Fig. 1, to tens, hundreds, &c., to any degree to which it may be desired to extend the capacity of the apparatus.

The carrying-disks 2? are supported on a shaft 28, carried by a frame 3-, composed of side plates 29 and 30, which are secured'hetween the side plates l1 and 12, being pivoted at their front ends at 31, (see Fig. 10,) so their rear ends can be raised or lowered to set the carrying-disks into and out of position to be meshed by the operating-wheel 26. In moving the frame 32 into andout of adding position I prefer to employ a rock-shaft 33, Fig. 26, hav ing a crank 34, connected hya pitman 35 with the rear end of the frame 32, and a crank 36, connected with a lever 37, which is operated in one direction by an eccentric 38 to lower the rear end of the frame 32 to set the carryingdisks into position to transfer the totals to the total-printing mechanism. This position is shown in Fig. 7. The frame 32 is raised at its rear end to position for adding, as shown in Fig. 6, when the eccentric 38 is released by means of the spring 39, operating u on the shaft 31-3. The purpose of thus adjusting the frame 32 is to permit the setting of such frame so the carrying-disks will be in position for being meshed by the opci'atiiig-\vlwel in the operation of adding, as shown in Fig. 6 and to permit the lowering of such carrying-disks from the position shown in Fig. l) to that shown in Fig. 7, in which latter ligure the opera! ing-wheel :Zli isadjnsied out of me h with the carrying-disks and the latter are meshed directly with the intermediate disks 4:0, so the total can he transferred from the accumulating disks -21 through the carryingdisks to the intermediate disks -10, and thence to the printing-whe ls 4'2. as will be more fully described hereinafter.

The accumulatingdisks ii, of which 1 use one for each of the carrying-disks, are meshed With their respective carrying-disks and are supported on a shaft -12, which is carried by the frame 'lhcsc disks 41. preferably have twen ty teeth and are arranged to transfer each to the next disk once for each ten of thei teeth. To this end I provide each accumulating-disk 41 with a pin 43, which projects at its outer end beyond the teeth of the disk 41 and is arranged at such outer end to be moved laterally, so its hcad like portion i will engage the teeth of the next disk in the operation of the apparatus. The pin 4 is pivoted at its inner cud at 43, Fig. 15, so its outer end can IllOVu laterally and engage at 50 with the next disk, and it is actuated by 50 the total.

for advancing the next higher one of the accumulating-disks is eilected by means of the oar 47, arranged across the front sides of the accu in Mating-disks and provided with inclined guides 48,(see Fig. 11,) formineone side to of slots 49, through which the pins 43 pass as theaccnmulating-disksareadvanced. 'lheinclined guide-surfaces 48 operate to push the pins 43 laterally over, so the portions 44 of said pins 43 will engage'with the nextdisk while 15 the pin 43 is passing throughthe har47. Thus the said next higher disk. will be advanced wii h the preceding disk one step while the pin 4-3 is passing through the bar 47, the pin springing, back out of engagement with the adjacent wheel when the pin has passed the said bar 47.

As the addition is eifected on the carryingdisks it is transferred therefrom to the accumulating-disks, and the total of addition is thus carried by the accninitiating-disks, it

2 5 corresponding to the steps to Which the pins 43 of the several accumulating-disks have moved forward in the direction indicated by "the arrow 51 in Fig; 14 from the bar 47. It follows, therefore, that if the number of steps the pins 43 are distant from the bar 47 cor- I responds with the total accumulated on the disks 41' then if said disks 41 be turned back in the reverse direction severally corresponding distances they will move a distance cor- 5 responding to the total, and if they be meshed with wheels which in turn mesh with the printing-wheels the latter will be automatically set to print the total. To thus set back the accnmulating-disks, I provide what for convenience of reference I term the totalcarrying bar 52, which swings over the accumulating-disks 41 to and from the bar 47. When swung hack in the direction indicated by the arrow 53 in Fig. 14, this bar 52 will en- 45 gage the projecting pins 43 and will move the same and their corresponding disks 4-. back to the bar 47, thus setting suchdisks back a numherof steps eqnali'ngthe numberof steps they have been previously set.- np in securing By this ineansI am able to set the printing-wheels to the total in a simple accurate manner. The bar 52 is carried by two arms 52 to which it is pivoted near its rear edge, so its forward edge can he set back out of the path of the pins 43 until such time 'as itis desired to transfer the total to the printing-disks. The arms 52 are pivoted on the shaft 42, and when in normal position the bar 52 lies on the side of the accnmulat 6o ing-disks opposite the bar 47, and the edge of the bar 52 next the disks is upturned (see Fig. 12) by means of a tripping-disk 54, which rocks on the shaft 42, is connected by a link 54 with the bar 52,'and is provided witha pro- 6 'ection 54 which is arra-n ed to abut a 'ainst a stop 55 to tilt the bar 52 relatively to its arms 52 to the position shown in Fig. 12,

when the pins on the disks can pass freely under it. A spring 56 acts in opposition to the tripping-disk and immediately resets the total-carrying bar to the position shown in Fig, 14, when the projection 54:" is moved out ofengragement with the stop 55. In this last position the bar 52 will engage ail the projecting pins of the accnmMating-disks which may project between it and the bar 47, so the total-bar 52 will carry such pins hack to the Zero at the bar 47 when the said bar 52 is operated for such purpose.

In operating the total-carryinn bar I provide its arms 52 with pinions 57, encircling the shaft 42". I employ one of these pinions 57 on each arm 52, hecanse thereby I connect and brace the arms 52 together, this be int, desirable because of the pivotal connection of the total-carrying bar with the said arms 5%. A shaft 58* has pinions 58 mesh ing with the pinions 57, and such shaft 58* is extended and receives a pinion 58, which when the frame 32 is lowered. into position for printing the total meshes with a gear 59, which in turn meshes with the pinion 18 on the shaft 13, so that if the 9 key be operatedatthis time it will tend to throw the total-carrying har hack a distance far enough to carry a 9 on the accnninlating-disks hack to the stopbar 47. i use the 9 key in this operation because by it I get the greatest throw of the parts, and it should he understood that the operation of the, 9 key at this time will not operate the adding devices, because in striking the total the open ating-wheel 26 is shifted laterally out of engagement with the said carrying-disks.

When the total is struck by turning the wheel 58, as described, and the said wheel 58 is lifted out of mesh with the wheel 5H, such wheel 58 and its shaft are returned,with the total-carrying bar, to normal position by means of a spring 60. This spring, 60 (see Fig. 26) in the construction shown secured to the frame and gear 58 and operates by its tension to return the said parts as desired.

Now, in operation, if the parts he .veryaccurately titted and are not worn or loose the bar 47 may he fixed and unyielding and form a solid stop against which to bring the totalcarrying bar 52 in setting back the totals for the purpose of transferring the same to the printing-wheels. I prefer, however, to arrange this l ar 4-7 so it will yield and may be depressed slightly, (see Fig. 14,)as thereby i am able to take up lost motion and move the adding-disks the desired distance to insure the proper movement thereof and of the intermediate disks to set the 'priniiinr-wheels to the desired point, as well as to insure the proper resettingof the carrying and intermediate disks to secure the proper engagement therewith of the detents 6i and U2 and Si, by which the parts are held from displacement by the momentum of themachine. To this end I pivot the bat-4:7 so it may be pressed at its end next tne accumulating-disks arid IIO support and return it by a spring 13. As the spring 63 returns the bar t7 when pressure thereon is releasethsuch bar 1-7, bymoving up the pins 43, will return the accumulating-disks, and thereby the carrying-disks, to bring the oarrying disks and intermediate disks to position to be properly meshed by the operating-wheel 26 when the latter is -moved to position to engage with the said carrying-disks. I therefore prefer to make the liar 47 depressible and to regulate the degree to which it may be depressed by an adjustable stop (54 on the frame, which is engaged by a projection on one of the pinions 58. Such projection 65 also engages a stop 64" on the frame and limits the motion of the pinion 58 and of the i.()l-il-CH.l'- rying ha in the return movement given it by the spring 50.

The p'rintine-wheels are carried by a frame 61, pivoted at its upper end at (53 a nd swingingat ils lowerend, where it supports the printi ng'avheelsni p to a position where it will print against the paper on the paper-carrier 64:. (See Fig. 3.) The handle :25 maybe operated to swing the frame ill. into printing position through the medium of the pit-man (35, (see Fig. lbllwhich connects its: crank 65 with the pullcywemion 2 3 to rewind the springilrum of the main shaft at each operation ol the printinn-frame.

The printing-wheels are each independently spriunmet-netted by springs do, which tend to automatically return hesanie to neutral position or one step beyond the zero-poin t when their detents 31 are released The detents 31 are actuated into engagement with the printing-wheels by means of spring 71, as shown. I release all of these detents 51 on he return movement of the printing-frame after each printing opera: ion has been ell'eoted, so that all lilt' disks which have figured in the printing opcral ion may be returned by thi-se springs lllj to the neutral position. To ell'ect this automatic release of the detents 31, which are pivoted at UT and have arms 68, I provide the rocking releasing-shaft (39, journaled in and swinginewith the printingl'ranie and having a in; or blade 70, which may be operated to engage the arms (SSof the dctents and release the latter from the printing-wheels. The releasin eshaft is operglted.

in one direct ion by the spring 71 and in the ypposite direct ion by the crank-arm 2 on tho shalt ill, illLil crank-arm 72 when operated in the 'Jill((fl ion of the arrow 713 (see Fig. ill) will more the shat: ift to release the detents.

Thus it will be seenthe springs 66 return the printing-wheels to their neutral positions after each printing operation, the detents 31 holding such wheels inany adjustment to which they may be set by the operating devices before described;

The printing-wheels are numbered from 0 up to 9, and in advance of the zeros I provide blank spaces, so the printing-wheels stand in normal position not to print, but to present blank spaces to the printing position. This is necessary, because in printing the printing- Wheels are all moved up bodily against the paper, and if they stood with the zeros in printing posit-ion all the disks that had notbeensetupto position would print0 both to the right and left of the printed figures. To insure the stopping of the printing-wheels in position to present the blank spaces to the printing position, I providostop devices consistingof projections t? on the printing-wheels, which engage projections 42 on the disks 42, which latter are fast on the shaft 42, on which the priuting-wheels'turn. This construction serves to stop the printingwheels accurately in their initial positions,

where they present blanks to the printing' line. {also provide a stop projection l2, which cooperates with stop 4;" to prevent the advancing of the printing-wheels be yond the li position in case the step-bystep feed mechanism shouldslip or become disarranged, thus preventing injury to the springs which operate the printing-Wheels. The printing-framealso operates when swung to printing position to release the detent devices of the mechanism for shiflingthe op crating-wheel to units, tens, hundreds, the. To this end I connect. the said detent Tl with a lever 75, which is engaged by a spring 76, whose tension is constantly exerted to release the detent. The printing-frame has a portion zit-1:77, (see Figs. 3, 16, and 18,) which when the frame is in the position shown in Fig. 3 bears under the lever 75 and operates to hold the said lever and its detent in opposition to thespring 76 and in position so the springactuated point 78 of the detent will be held in position for engagement with the rack-bar 7H for holding the opcratingovheel in its dit' ferent positions. When the n'inting-l'rame is swung to printing, position, its portion at 77 moves out oteugagement with the lever 75 and the spring 76 will operate the lever T5 to lift the spring-point T8 of the detent clear of the rack-bar 70, so the latter can return to its starting-point under the action ol' the spring 135, presentlydescribed. This rmwkdntr'Til is operated step by step by the pawl-lever so, which pivoted at 8i and is connected by a link with the crank 83 on the rock-shaft St. The rock-shaft 84 (see Fig. in) also has a crank S5,which is c nnected by a link SE5 with one arm 87 of the bell-crank lever 8%, whose other arm 89 is connected at 90 with the keylever 91, by which the operating-wheel is set up as desired.

The operating-wheel 26 is keyed on and movable along the main shaft 13 and rests while in neutral position in the position shown in Fig. 1 to the left of the carrying-wheels 27. When it is desired toset up an figure in the units, tens, hundreds, (he, the operatingwheel is adjusted from the position shown in Fig. 1 to the right one, two, or more steps, as desired. This lateral shifting pf the operating-wheel is effected by the frame 92, which has its side bars 93 94 sliding at one end on the main shaft 13 and at their other or rear ends on the guide-shaft 95, which journalsin the plates 11 and 12. The frame 92 is thus slidahle laterally on the shaft 13, and as it so slides it shifts the operating-wheel from its neutral position to mesh with any desired one of the carrying-disks. The frame 92 is connected with the rack-bar 7i) and is shifted to the right from the position shown in Fig. 1 by the lever-pawl operati ng on said rack-bar, as before described. As hest shown in Fig. 6, the setting-wheel 26 hasa huh orsleeve which extends through the iever 96 and side bar 94: and has fixed upon it outside the bar 94a col lar which operates to retain the parts in proper position. When the operating-Wheel is shifted into mesh with the desired one of the carrying-disks 27, it is also meshed with the corresponding one of the intermediate disks, so the action of the operatingo heel in setting up the carrying-disks and accumulating-disks to any desired degree will also set up the printing-wheels through the action of the intermediate disks, as will he understood from Fig. When theoperatine -Wheel is thus set to mesh with any desired ones of the carrying-disks and intermediate disks, if the operatingwhcel he moved one point it will set the printing-wheel upone point. and will thus set. the said Wheel to print 0, as the printing wheels stand normally at a blank ornentral posititnnso t hose printi rig-wheels which have not neon set up will not pt'intat all when the frame (it is raised to printing.position. To remedy this I provide the zero-settimpnp devices, which include a lever 96, pivoted between i s ends on the sleeve or hub of the operatingwheel :26, having at its forward end a yielding spring-actualed pawl or point 96 to engage with the proper intermediate disk =10 and arranged at its rear end for operation by the forward end of a lever 97, which is pivoted at. .18 on the shaft and has its rear end siiding on a rod 99, which connects two crz-tnlz-arms it'll), extending from the opposite ends of the shaft 95, he rod 99 operates the'lever 97, being moved up anddown by the link 10i, which connects one of the crank-arms 100 with the crank-arm lO2 on the shaft 103, which also has a crank 10 1, connected by the link with the key-lever 106, by which it is tn erated. ,(See Fig 19.) It will he noticed that the zero -setting-up pawl is in advance 01 at the right of the operatingwheel when viewed from the rear, as in Fig. 1, so the said pawl is in position to set up the zero of any of the printing-wheels before the operatingwheel is set upto position to operate the said wheel.

It will he understood that I operate the zero setting up devices independently of the spring-moton as the total device is in gear with such motor, and if I employed it for setting up the zero it would add one for every zero so set and would thus aifect the column of figures accumulation".

The eseaptment; releasing mechanism is best illustrated in Figs. 21,22, and 23. This mechanism includes a wheel 10?,whieh isiixed on the shaft 13 and composed of a rim 10S,

havine a Web 109 and a plate 110.- The rim 108 has a series of openings 108, parallel to the shaft 13, and radial openings 111 through the inner side of the rim and intersecting, the ope'nincs 108 The plate has radial openings 112, communicatingat their outer ends with the openings 111, and this cover-plate llC' fits within the rim 108 and against the web 109, being secured in place h" the screws 113. Pins 114 play in the openings" 108 and are provided with grooves 115 and ill), entered by holding-pins 117, which are arranged in the openings or ways 112 and are forced outward into engagement. with the pins lit to hohi said pins in either positi n-thatis, entirely within the rim when the pins 117. are engaged in grooves 115 or projecting: from the inner face of the rim against the stopplates 107* when the pins 117 are engaged in the groove 116, as will he understood from Fig. 23. The openings 108* in the wheel 107 are arranged a distance apart sufficient when the wheel is moved from one step or from one hole 108 to the next to move the operatingwheel one step or one tooth. Alon; the outer side of the wheel 107 I support a guide-plate 11.8, having holes 118 in alinemenhwith the holes 108 and receiving the pins 119, which ,are also guided in a plate 120 and are actuated normally outward or away from the wheel 107 by the springs 121. Each of the pins 11.) is connected with its corresponding disk 122 by a pi'ttnan 123, and such disk is connected hya pitman 124 with its operating key-lever 125, so that when such key-lever is depressed it will operate its disk 122 to cause the pittnan 123 to force the pin 119 against the pin 114 and force the said pin from the position shown in full lines, Fig. 21, to-the position shown in 2 In this last position the pin 114 will protrude beyond their]- ner face of the wheel it)? against the plate ITO 107 and form a step to ahut the end of the theinner end ot a collar P29, which is slidout of tlte patlt of the ends of the pins 114,

which are protruded from the inner face of wheel 107 by theaction of the pins 119, as be fore described. A spring 134 also engages the do 126 and tends to force the same outward into the path of the protruded ends of the pins 114. In the operation of this construction as one of the key-levers 125, which are numbered l. to 9, inclusive, is operated, it will push out its corresponding pin 119,

which in-turn will force its pin 114 to pro-.

trude beyond the inner face of thewheel 107 and into the path of the escapement-dou. Such movement of the pin 119 will cause its lever 1:27 to operate through the collar 129 and lever 132 to move the dog back clear of the precediu; pin 114. 'All this time the pin 1l9 extends partly within the opening 108 in the wheel 107, detaining said wheel. Now if the key-lever he released and the pinlist be withdrawn the wheel 107 and the main shaft will be moved by its spring-drum until the projected pin .ll strikes upon the capementwdog, the distance varyins, according to the key struck, the 1 key moving the main shaft one step, the 2 key moving it two steps, the; This is regulated according to the distance the pin 119 corresponding to such key stands from the escapetnent-dou. After the pin 11% has passed below the upper end of the dog 126 the outward movement of said dog will operate to force the pin 114: back tothe normal position shown in Fig. 21. If for any reason the pin is not so readjusted by the dog 126, a cam-surface 125, arranged in the path of said projecting pin 114, will operate to force the said pin positively back to its normal position.

From the foregoing description it will be seen that I provide means for moving the operating-wheel to set it into mesh with any one of the carrying and intermediate disks,

and the said wheel can then be operated by the step-hy-step mechanism to advance such disks to set up any desired numheron the accum ulatins-disks and onthe priuti rig-wheels.

ILwill also be remembered that prior to setting the operating-wheel into mesh with one of the intermediate disks it is desired to operate the zero-settingnip device will be operated to move the printing-wheelcorresponding to such disk up to 0.

The rack 79 is opprated by the lever-pawl 80 to move the operating-wheel into engagement with the several disks, units, tens, hundreds, 650, Thus if it be desired to print, for instance, the number .f 12a, the zero-setting-up device will first be operated to move the units-printing wheel up to 0. The operating-wheel is thus brought.into mesh with the units-carrying and intermediate disks by means of the rack 7.) and pa wl-lever St) and .00- operating parts and the 4 key-lever is operated to permitthe escapementt mechanism to move up font-steps, thus moving the main shaft and the operatin wheel fou r steps, so the units-accuminulatinu disk and the unitsprinting Wheel will he moved up four points. For the next figure (2) the zero-selting-np device will be operated upon the tens-wheel and the operating-wheel then set-up to mesh with the tens carrying and intermedia e disks and then operated to move sut-h disks up two points. The 1 will likewise be set up on the hundreds-disks, completing the number 124. At this time the operatingwheel stands in mesh with the hundredstlisks of the sets of carrying, and intermediate disks, being held in such position by the engagement of the spring-actuated point 78 of the detent with the rack-bar 79. As the printing frame is swung up to print the 12; on the paper tlte portion 77 will move out from under the lever 75, when the spring 76 will operate said lever to lift. the detentpawl 74 out of engagement with the rack-har 79, so the said bar will be returned by the spring 135 operating the crank-arm 136,whose wrist-pin 137 bears against the frame 912 and tends to return said frame and the op6ralin}{ wheel and zero-setting-up device to the starting position, as shown in Fig. l. If now another numbersa 4l2be printed in the manner before described, it will be understood from the previous description that on the accummulating-disks, the units one of such disks being moved six points, the tensdisk three points, and the hundred'sflisk five points from the stop and guide-bar t7. To print the total, the eccentric -38 is operated to lower the rear end of the frame 32, so the carrying-disks will be brought-directly into mesh with the intermediate disks. 'lhisadjustment of the frame 32 to bring the carrying and, intermediate disks into mesh with each other also adjusts the gear 58 into mesh with the gear 59, which is also meshed with the gear 18 of the main shaft. It now the 9 keylever be depressed, the shaft-13 will be released and will, through the gears 18, 59, and 58, operate the total-transfet'ring bar to move the pins a3 back to the'stop-bar and so transfer the total to the printingwheels, which may be operated to print the same upon the paper carried by the papercarrier.

In the described operation it will be noticed the printing-frame 61 swings into the basket 138 of the type-writer, prints in alincment with. the type 139 thereof upon the paper carried by the paper-carrier 64, and cooperates with the type-bars }4 l', ,forming a part of the glistening devices of the typ'ewriter. By. this means the apparatus mpydee"conveniently the total of 12%, and n2 will he set'up- IIO
